This is a most excellent place for technology news and articles.
If you are going to go on the day before, I'd recommend doing your shopping at 5:00am and be done by 06:00 am. That's when the day shift comes in. I wouldn't bring a cartful of groceries to the check stands before that time though, nite crew will be stressing out.
